An effort to understand Earth’s past climates uncovered a history of wild temperature shifts and offered a warning on the consequences of human-caused warming.

A new study co-led by the Smithsonian and the University of Arizona offers the most detailed glimpse yet of how Earth's surface temperature has changed over the past 485 million years.

Researchers created a curve of global mean surface temperature throughout deep time, providing context for understanding today’s climate change hurdles.

We live in a rapidly warming world. Immense volumes of human-generated greenhouse gases are nudging Earth’s climate to a warmer and warmer state, further changing our planet as sea levels rise, living things shift how they live,

A recent study published in Science unveils a detailed curve of global mean surface temperatures that highlights Earth's temperature fluctuations over the Phanerozoic Eon, a period when life diversified and survived multiple mass extinctions.

A recent study confirms that Earth's temperature is strongly correlated with the amount of carbon dioxide in the atmosphere.

If you were to compare Earth today with the planet 485 million years ago, when would it be warmer? A new research study charting temperatures over nearly half a million years reveals the surprising answer.
